To allwltov1zz'may concern: Y l' Be it known that I, BENJAMIN of the city of New York, borough oBrooklyn, in the county of Kings andfStatefcf New York, have invented a new and Im proved Engraving-Machine, oit which theV following is a full, cle-ar, andexact descrip'- tion. i

The invention relates to machines. such as shown and described in the Letters Patent ot' the United States for an etching machine, No. 1,039,713 granted to VViiliam S; Eaton, October l, 1912.

The object of the Invention is toprovidel` a new and improved attachment *toren-ch types of'inachine W'hereby'the operatorisenabled to accurately space letters, ninnerais, signs or other charactersirrespective of their width and shape.

ln order to accomplish the desired result, the work bed, carryinga coatedplate,'is

mounted to slide sidewiseinnder thelengraving needle and a spacin .device is connected with the saidivork beto shift the-latterV sidewse. Use is also made of a master plate or pattern provided with" letters of the alphabet or other characters, anclpositioning marks one associated with eac-h character at the itranen/cree" centerflthereof to :pere

mit. of properly positioning each character L relative to the 'stylus Avofwthe transmitter. Use is also made lofftvro cmnpleinentary charts having horizontal "space'sjionjfwhich indicates .the .pointeri of thejf spacing device,f sundry of the spaces beingiprovidedwithi' characters according to their widthgfeach space representing a predetermined spacing unit onthe plate tohe engraved. i rfi* 511 A practicahembodiment cf the invention ings forming` a partici thisspeciicationyin which similar characters of? reference indib cate correspond-ing parts in ali the vfi'eiais- Figure l isa rontelevation of thefenl Fig. bis aside elevation of" the sain-ev;

The lower end ofl the transmitter 50 carries a 4stylus 60 adapted to trace letters of the alphabet, numerals or other characters 61 formed on the master plate 62l mounted to slide sidewise in a plate holder 63 provided vvith a clamping lever 64 for locking the master late tempbrarilfvin place'in'the holder'l63, tia isydurln `the time the stylus is movedA along the out inesfof the charac; ters 61 to be engraved at thel time byY the needle 30 on the plate 28. rBhe plate holder 63 is supported' on aljrauxiliariv tablefiattacked to the table 20 and the holder 63 is sidewise adjustable on the auxiliary table 65 Vby the use of clamping screws 66 extending in ya longitudinal slot 67 formed on the auxiliary' table 65.

The ball 92 is adapted to be moved into release position relative to the shifting rod 82 by the use of a release rod 93 mountedy toslide in suitable'bearings arranged on the head 90,.y The release rcdf 93 is pressed` on by a spring 94 to re-InfiallyJ hold the same in outermost position to allow the ball 92 to grip the shifting nod 82, as previously explained. The outer endof the release rod 93 is provided with a handle 95 under the control of the operator for pushing the release rod 93 from the right to the left to disengage the ball 92 from the shifting rod 82 whenever it is desired to quickly return the Work bed 26. In order to holdf the shifting rod 82 against accidental return movement during;A the returnl movement ofl the work bed 26, use is made off another gripping ball 96 mounted in eninclined opening. 97 formed in the bearing 841, previouslg mentioned, and the ball 96 is pressed on y aspring 98 to hold the ball in firm Contact with the shifting rod 82 for locking the latter against return Inovement. A springfpressed rod 99, similar to the releasin, a;4 rod 93,` is adapted to engage the ball- 96 to move the latter out of grippingl engagement with the shifting rod 82 whenever 1t is desired to shift the lat-ter and the Work bed 26 by hand from the left. to the righ-t.

Spring clips 167, 168 overlie the side margins of the charts 165, 166 to hold the same against accidental displacement while in position on the table 160. The charts 165, 166 are provided with horizontal spaces 170, 171 containing letters of the alphabet, punctuation signs or other characters 172 and 173 arranged according to their width, `that is, characters of the same Width are arranged in .one space and characters of another Width are arranged in another space. The characters 172 on the chart 165 are arranged in the spaces according to their width, beginning with the lowest space for the nari-cwest characters and with the upper spaces spaced for the Widest letter. In a like manner the char acters173 are arranged in the space 171, beginning with |the narrowest characters on the uppermost space and With the Widest characters on the lowermost space. The charts 165 and 166 are held spaced apart more or less according to the spaces to be given to the adjacent characters of the matter to be engraved. VVhen the pointer 161 stands intermediate the adjacent lower and upper edges ofthe charts 165 and 166 then it is in zero position. The characters 172 and 173 correspond in style and Width to the characters Gl on the master plate 62, and it `is understood that with master plates having `characters 61 of different styles correspond- .186 attached to the front of the forward .guideway ,23 of the support 22. The scale 180 is provided near its upper margin with a linear graduation 181 (see Figs. 9 vand 10) representing inches, subdivided in ten parts,

With 'zero at the right-hand side 'of the Near the lower mar in of the scale 181) is arranged a secoxid inear igradu-ation 182, scaled 1 to 2 relativeto the graduation 1181, with theY zero mark (0) yopposits the -inchmark `on the graduation 181 andwith the scaled or proportioned inches i extending to ther-ight and the left in conP-` secutive order. .On the graduations 181 and 182 indicate two `pointers 183 and 184 attached to or forming gert of anvfarm 185 secured to the front gui ointers 183 and 184 move eway 25 ofthe Work 10inch mark of the right-hand portion of the graduation L82.y When the ointer 188 is at the -inch mark of the gra( nation 181 then the pointer 184 is` at the'zero mark of the graduation' 182. The said pointersare now in vertical alinement with the needle 30, the axis of the transmitter and the mark 69 onthe auxiliary bed 65 (see Fig. 1).

By reference to Fig. 2, it will be notieed that the axisofthe? pivot 107 is ina horizontal plane extendingthrough the axis of the universal connecting jointV 51 connecting the transmitter 5G with the'carriage 34, andthe axis ofthe pivot 1-11 is iii-the seinehori zontal plane asthe axis of the universal joint 52 hung inthebracket 53. When the universal joint 52 is shifted in the bracket 53, a corresponding adjustment is made of the screw 113 in the bracket 114 to maintain the above described relation between the axis of the pivot 111 and that of the universaljoint 52.` The axis o the pin 117 is in the same horizontal plane as the point of the stylus' 60; By the arrangement described the sidewise movement of the stylus on any one character 61 is proportionate to that given by the shifting lever 109 to the work bed 26ai1d'is according` to the spacing distance leid out on the charts relative to the correspondingcharacter, so that the character engravedon the coated plate correspondsin widthi to theV shifting movement gwen `to the work bed at the time.

The operation is as follows:

Presuining.- thatthe severalV pants are in the position illustrated'in Figs. 1 lend 2 and it is desired to engrave the word JOI-IN Centrally on the coated plate 287 then the operator first moves the work bed 26 to the right until the pointers 183and 184 register with zero and 100i the graduations 181, 182, es indicated in Fig. 9. The pointer 161 of the spacing device is inizero position, that is, between the adjacent lower-and u' per edges of the' cherlzsrlfaud 166,' andftliis starting 'position is' .repesentedl'by' an imaginary starting marit' 201 (seeFlgs. 12,131and14f);
